Answer:
The lines ared skew
Step-by-step explanation:
First we check if they are parallel. To do this we compare the ratios of the slopes of each component, and this should be the same:
As we can see the ratios are different so they are not parallel lines.
Now we test for intersesction:
we have to equate each component and solve it as a system:
- 3-2t=-1-u
- 7+4t=18+3u
- -3+8t=7+2u
From equation 1: u=2t-4 we replace this in eq. 2
From equation 2: t=1/2 replacing both in equation 3 should give us an identity
From equation 3: we reach 1=3 as this is not true, out hypothesis that the lines intersect is wrong.
Since this lines are not paralel and don't intersect we must conclude that the are skew
Answer:
Second choice
Explanation :
The postulate that is used in order to prove the congruency of the triangles is the ASA which means (Angle – Side – Angle). The property that is applicable for the congruency of DB to itself is the reflexive property. Therefore, the answer to this item is the second choice.
Hope I helped! :)
If yes mark me BRAINLIEST!

Answer:
1.75
Step by Step:
Use the distributive property first.
(3.5 x 2.25) (3.5 x X) = 14
7.875 + 3.5x = 14 Now subtract 7.875 from both sides
3.5x = 6.125 Now divide 3.5 by both sides
x = 1.75
This in what I got:
(-7i)(10i)
-70i
Answer:
If between 6 friends, each got 16 by dividing. Doing multiplication will give us our variable. 16(6)=g
Step-by-step explanation:
16 g per friend
6 friends total
16 times 6= total g
16(6)=96
g=96
